Adobe audition has its fantastic multiband compressor but did you know you can get fantastic audio compression from a free plugin to audacity.
Change noise floor in audacity.
Then i selected the silent parts of an audio sample that i sent you guys that had a bad noise floor problem and that number is also 12.
It will eliminate the noise while at the same time maintaining the audio integrity.
Artifacts can happen if the noise floor is higher than was estimated.
Using a sample late in.
The level above which compression is applied to the audio.
Noise reduction is the constant challenge for the recording engineer as perhaps the most significant aspect of improving recording quality following the advent of realistically priced recording hardware and free software like audacity anyone now can be their own recording engineer and grapple with the same problems.
Under the effect tab you will find noise reduction command under the drop menu.
Release time 10 12 secs.
Occasionally my noise floor will be perfect just below 60 and i will get a full pass on the test but i m recording in the exact same room with the exact same settings as my too low tests so i don t know why there is a discrepancy.
Step 2 reduce the noise.
My secret audacity recipe for great audio compressors 50.
Click noise reduction tab.
Noise floor 40db.
Is there any way to increase the volume of my noise floor through audacity to exactly 60 db.
The compressor adjusts the gain on audio below this background level so as to prevent it being unduly amplified in processing.
Attack time 1 5 to 1 9 secs.
To optimise the performance of audacity s noise reduction it is best to use a noise sample near the beginning of the tape rather than the end.
Try these settings to play around with.
The benefit of look ahead is that sudden peaks do not pass through the effect before the gain has had time to change.
Click get noise profile this audacity feature will determine the type of noise in your audio.
There s a window below that get noise profile button i selected a silent section of a published audio book and the noise reduction db is 12.
Try to keep it between 15 to 18 db.
Threshold 15 db to 18db.
Use a limiter to keep your db range locked in.
